Unit Operation > Radio Page Scanning and Monitoring The Scan option allows you to scan through the available channels for activity. As the unit scans and detects activity on a channel, it pauses on that channel/code for a few seconds, then continues scanning. If you transmit at that time you will be on that channel. When the Rino 520/530 is scanning and it receives an incoming signal, the Rino 520/530 automatically decodes the Code used by the incoming signal. The Rino 520/530 then uses that Code when it transmits back to that unit. However, if you transmit when the scan has not paused, the transmission uses the channel set before scanning. You may use the Set Scanlist option to pick which channels/codes to scan. Scanning through all channels can take time: Selecting only specific channels/codes decreases the scan time and helps prevent the chances of missing a transmission. The Scanlist also has Option Menu choices to Scan Current Codes or Scan All Codes. Choosing Scan Current Codes scans only the Channel and Code combination in memory. The Monitor option lets you listen to a single channel for all activity, including static and weak signals. The Rino requires the user to adjust the squelch for a frequency to filter out unwanted noise. Using the Monitor option temporarily turns off the squelch, allowing you to hear the open channel. If you see an "Activity..." message, there is activity on your selected channel, but the incoming signal does not match the Code your unit is using. You may choose to monitor a channel if you want to hear all the activity on a channel. To scan or monitor a channel(s): 1. Using the Thumb Stick, highlight the Scan or Monitor button and then press the Thumb Stick In. Scan starts searching through the available channels. Monitor opens the channel to listen to any radio transmissions on that channel. 2. To stop using either option, highlight the button with the Thumb Stick and press In. 12 Rino® 520/530 Owner's Manual
